An iridium compound, chloro-carbonyl-bis(triphenylphosphine)-iridium, in solution, takes up molecular oxygen-one molecule per metal atom-which is subsequently recovered by reducing the pressure. The adduct is photosensitive but otherwise stable at ambient temperatures. It is a monomeric molecular complex and probably contains a peroxo group with both(More)
The rates of oxygenation and deoxygenation of a series of iridium complexes increase and decrease, respectively, with increasing electron-releasing tendency of the anionic ligands (A) attached to the metal atom in the oxygencarrying compounds, [IrA(CO)(Ph(3)P)(2)]. Calculated heats of oxygenation (-DeltaH(2)(0)), related to Ir-O(2) bond energies, are(More)
Chlorocarbonyl-bis(triphenylphosphine)iridium(I), in solution, reacts reversibly with carbon monoxide under normal conditions, one molecule per metal atom. Formation of a 1 : 1 metal complex-CO adduct is verified by CO absorption measurements and the infrared spectrum of the adduct measured in situ. The spectrum suggests that the metal-C-O bonding is of the(More)
